I didn’t really expect anyone to know that, which was sort of the joke. He was very famous in his time, but by now it’s a bit of a deep cut.
Artie Shaw was a clarinetist who ran a jazz band. In addition to that, he was also quite the weirdo. Womanizer, liked math a lot (like more than is natural), was an expert marksman who was nationally ranked in that sort of thing, and really into fly fishing. Also, currently, very dead. And that’s good because otherwise he’d be 114.
